Grassland Management

California naturalized annual and perennial grassland is the most abundant vegetation type on the refuge, covering over 9,000 acres of the refuge. These areas are dominated by a variety of annual grass species, mainly of Mediterranean origin.

It is the Service’s goal to protect and enhance Bitter Creek NWR grasslands to promote ecologically sound conditions to support a diversity of migratory birds and special status plant and animal species. 


To achieve this goal, the Service has developed specific management actions. Beginning in the fall of 2014, we will be implementing and evaluating a limited prescribed grazing program to help achieve grassland objectives. For more information about this program, please see our Comprehensive Conservation Plan and Prescribed Grazing Plan or contact the refuge manager at (805)644-5185 or
